This Research aims to determine (1) History, actors and the causes of conflict in terms of the social aspect of economic, cultural and institutional happened in PFMU Model Poigar (2) Recommendations settlement to parse tenurial conflicts PFMU Model Poigar. Data analysis method used is a qualitative approach. The results showed that land claims by communities began of forest utilization activities to meet basic needs. Tenurial conflicts PFMU Model Poigar is a structural conflict. Some of the main actors should receive priority attention is the processing community land in the area and local employers. Some of the basic causes of conflict tenurial PFMU Model Poigar is a lack of understanding about the existence of related parties PFMU Model Poigar, the dualism of authority, lack of community empowerment, and law enforcement is still weak.Based on consideration of the history, the actors involved and the cause of the conflict, then some of the recommendation of this study is the institutional strengthening KPHP Poigar model, the development of that partnership, and law enforcement.

Shorea assamica Dyer is one of the forest trees with recalcitrant seed type, It can not be stored for long periods. Storage technique of planting material in the form of seedlings is one solution that can be done to overcome the problems of the seeds with a short shelf life. The aim of the research is to determine the growth response of S. assamica seedlings to shading andgrowth inhibitor treatments. Research design was approached by split plot design. The main plot was shade and sub plot was a growth inhibitor. The storage conditions consisted of (1) light (38,600 47,200 lux), (2) medium (19,342 35,300 lux) and (3) heavy shading (62 2,106 lux). The inhibitors used were (1) paclobutrazol 250 ppm , (2) NaCl 0.5% and (3) aquadest (as a control). The results showed that the combined treatment of paclubutrazol 250 ppm with heavy shade was able to suppress the growth of height, dry weight of root and seedling quality index of S. assamica at the age of 6 months optimally in nursery.

Pengaruh perlakuan cekaman kekeringan terhadap pertumbuhan semai cempaka wasian, nantu, dan mahoni Arif Irawan; Hanif Nurul Hidayah; Nina Mindawati

Climate change has shortened the rainy season compared to the dry season in North Sulawesi. The El Nino phenomenon occurred in 2015 had an impact on the death of clove plants due to drought. Drought stress testing on several types of forestry plants in the North Sulawesi area is a matter that needs to be done in line with these conditions. Development of cempaka wasian (Magnolia tsiampaca (Miq.) Dandy), nantu (Palaquium obtusifoliumBurck), and mahoni (Swietenia macrophylla King) plantations have been carried out by communities in North Sulawesi for a long time and have very good prospects. The research was done by conducting a simulation test at seedling level with treatment to be tested on volume and interval of watering. The watering volume consists of 3 levels, i.e.100%, 50%, and 25% watering of the field capacity, while the watering intervals included once-daily, 3-day and 5-day watering once for 18 weeks. The results showed that nantu species has better resistance to drought stress conditions compared with mahogany and cempaka wasian.
